Online Social Network-dataset now available

November 10, 2009

The Online Social Network-dataset used in my Ph.D. thesis is now available on the Dataset-page. This network has also been described in Patterns and Dynamics of Users’ Behaviour and Interaction: Network Analysis of an Online Community and used in Prominence and control: The weighted rich-club effect and Clustering in weighted networks. The network originate from an online social network among students at University of California, Irvine. The edgelist includes the users that sent or received at least one message during that period (1,899). A total number of 59,835 online messages were sent among these over 20,296 directed ties.

Welcome

Tore OpsahlMy aim for this blog is to explore and throw out in the open some of the ideas about social network analysis that I have, but no time to implement. Many of my ideas stem from my interest in weighted networks and my belief that the weights are an enormous source of data. However, many social network measures require that the weights are discarded. In so doing, the richness of the data is considerably reduced. In turn, this limits the analysis.
